Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT 
PRE-TENSIONER"

INFOID:0000000005531165

The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along

with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain

types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS

system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front

air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.

Information necessary to service the system safely is included in the SR and SB section of this Service Man-

ual.

WARNING:

• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in

the event of a collision which would result in air bag inflation, all maintenance must be performed by

an authorized NISSAN/INFINITI dealer.

• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal

injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag

Module, see the SR section.

• Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this

Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or har-

ness connectors.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS

WARNING:

• When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-

tion ON or engine running, DO NOT use air or electric power tools or strike near the sensor(s) with a

hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing

serious injury.

• When using air or electric power tools or hammers, always switch the Ignition OFF, disconnect the

battery, and wait at least 3 minutes before performing any service.

Precaution Necessary for Steering Wheel Rotation After Battery Disconnect

INFOID:0000000005259218

NOTE:

• This Procedure is applied only to models with Intelligent Key system and NATS (NISSAN ANTI-THEFT SYS-

TEM).

• Remove and install all control units after disconnecting both battery cables with the ignition knob in the

LOCK

 position.

• Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work.

If DTC is detected, perform trouble diagnosis according to self-diagnostic results.

For models equipped with the Intelligent Key system and NATS, an electrically controlled steering lock mech-

anism is adopted on the key cylinder.

For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and

steering wheel rotation will become impossible.

If steering wheel rotation is required when battery power is interrupted, follow the procedure below before

starting the repair operation.

OPERATION PROCEDURE

1. Connect both battery cables.

NOTE:

Supply power using jumper cables if battery is discharged.

2. Use the Intelligent Key or mechanical key to turn the ignition switch to the 

ACC

 position. At this time, the

steering lock will be released.

3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be

rotated.

4. Perform the necessary repair operation.

5. When the repair work is completed, return the ignition switch to the 

LOCK

 position before connecting

the battery cables. (At this time, the steering lock mechanism will engage.)

6. Perform a self-diagnosis check of all control units using CONSULT-III. 

Precaution for Working with HFC-134a (R-134a)

INFOID:0000000005259217

WARNING:

• CFC-12 (R-12) refrigerant and HFC-134a (R-134a) refrigerant are not compatible. If the refrigerants

are mixed compressor failure is likely to occur. Refer to 

HA-4, "Contaminated Refrigerant"

. To deter-

mine the purity of HFC-134a (R-134a) in the vehicle and recovery tank, use refrigerant recovery/recy-

cling equipment and refrigerant identifier.

• Use only specified oil for the HFC-134a (R-134a) A/C system and HFC-134a (R-134a) components. If

oil other than that specified is used, compressor failure is likely to occur.

• The specified HFC-134a (R-134a) oil rapidly absorbs moisture from the atmosphere. The following

handling precautions must be observed:

- When removing refrigerant components from a vehicle, immediately cap (seal) the component to

minimize the entry of moisture from the atmosphere.

- When installing refrigerant components to a vehicle, do not remove the caps (unseal) until just

before connecting the components. Connect all refrigerant loop components as quickly as possible

to minimize the entry of moisture into system.

- Only use the specified oil from a sealed container. Immediately reseal containers of oil. Without

proper sealing, oil will become moisture saturated and should not be used.

- Avoid breathing A/C refrigerant and oil vapor or mist. Exposure may irritate eyes, nose and throat.

Remove HFC-134a (R-134a) from the A/C system using certified service equipment meeting require-

ments of SAE J2210 [HFC-134a (R-134a) recycling equipment], or SAE J2209 [HFC-134a (R-134a)

recovery equipment]. If accidental system discharge occurs, ventilate work area before resuming

service. Additional health and safety information may be obtained from refrigerant and oil manufac-

turers.

- Do not allow the refrigerant oil to come in contact with styrofoam parts. Damage may result.

Precaution for Procedure without Cowl Top Cover

INFOID:0000000005259219

When performing the procedure after removing cowl top cover, cover

the lower end of windshield with urethane, etc.

FUNCTION DIAGNOSIS

IN-CABIN MICROFILTER

Description

INFOID:0000000005259221

FUNCTION

The air inside the passenger compartment is filtered by the in-cabin

microfilters when the heater or A/C controls are set on either the

recirculation or fresh mode. The two in-cabin microfilters are located

in the front heater and cooling unit assembly. The rear heater and

cooling unit assembly only draws in air from the passenger compart-

ment to recirculate into the passenger compartment, so the rear

heater and cooling unit assembly is not equipped with in-cabin

microfilters.

REPLACEMENT TIMING

Replacement of the two in-cabin microfilters is recommended on a regular interval depending on the driving

conditions. Refer to 

MA-9, "For North America"

. It may also be necessary to replace the two in-cabin microfil-

ters as part of a component replacement if the in-cabin microfilters are damaged.

REPLACEMENT PROCEDURE

1. Open the lower glove box and press in on the sides as shown so

that it will open completely, allowing it to hang by the cord.

2. Push down on the lock tab and remove the in-cabin microfilter

cover as shown.

3. Remove the in-cabin microfilters from the front heater and cooling unit housing.
4. Insert the first new in-cabin microfilter into the front heater and

cooling unit housing and slide it over to the right. Insert the sec-

ond new in-cabin microfilter into the front heater and cooling unit

housing as shown.

NOTE:

The in-cabin microfilters are marked with air flow arrows. The

end of the microfilter with the arrow should face the rear of the

vehicle. The arrows should point downward.

5. Install the in-cabin microfilter cover making sure the lock tab is

securely locked in place as shown.

6. Close the lower glove box completely.
